OPTICAL ANALOG-TO-DIGITAL CONVERTER Russian patent published in 1998 - IPC

FIELD: optical signal processing equipment, in particular, optical communication and information transmission systems. SUBSTANCE: device has optical amplifier, coherent light source, input optical splitter, optical waveguides, optical encoder, input of optical amplifier serves as device input. Its output is connected through optical waveguide to input of first optical element in serial circuit of N two-state optical elements which inputs are optically connected through optical input splitter to output of coherent light source. Inverse output of each of two-state optical elements is connected through optical waveguide to input of next element in circuit. Direct outputs of two-state optical elements are connected to corresponding inputs of optical encoder, which outputs are designed as permitted binary combinations serve outputs of device. EFFECT: increased speed. 1 dwg
